【摘要】 ①目的　探讨氢氧化钙糊剂对根管的消毒作用。②方法　用氢氧化钙糊剂或甲醛甲酚分别对 82例病人 10 6颗患牙的感染根管消毒 ,封药后 7d观察疗效。③结果　氢氧化钙糊剂消毒的成功率为 86 .8% ,甲醛甲酚消毒的成功率为 5 6 .6 % ,两者比较差异有极显著性 (χ2 =11.90 ,P <0 .0 1)。④结论　氢氧化钙糊剂抗菌作用强 ,是一种理想的根管消毒剂 ,作为换代的根管消毒剂可取代甲醛甲酚。更多还原

【Abstract】 Objective\ To study the disinfection effects of calcium hydroxide paste on root canals.\ Methods\ Calcium hydroxide paste and formo cresol were used separately to fill 106 infected root canals(82 patients) for disinfection, the efficacy was evaluated 7 days after the filling.\ Results\ The success rates of calcium hydroxide paste and formo cresol were 86.6% and 56.6% respectively, the difference was obvious( χ 2=11.90, P <0.01).\ Conclusion\ Calcium hydroxide paste has strong antibacterial function. It is an ideal root canal disinfectant and may be used to replace formo cresol.更多还原
